AI Technical Summary
During operation, dust particles can easily enter the wear gap between the chisel and the outer sleeve of the hydraulic breaker, causing internal damage and affecting its service life.
A dust cover is tightly fitted onto the drill rod. The end face of the dust cover extends outward radially and abuts against the outer sleeve. The dust cover has a fastening groove and a clamp to seal the wear gap and prevent dust from entering.
This improves the dustproof performance of the hydraulic breaker and extends its service life.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model belongs to the technical field of breaking hammer, and relates to a breaking hammer, in particular to a breaking hammer dustproof structure. BACKGROUND
[0002] In the process of continuously operating the breaking hammer drill rod, the outer sleeve matched with the drill rod and fixed on the front cylinder is abraded between the drill rod and the outer sleeve, and the working environment of the breaking hammer splashes dust particles, which easily enter the abrasion gap between the drill rod and the outer sleeve, causing internal damage of the breaking hammer and affecting the working life. SUMMARY
[0003] The utility model discloses a kind of breaking hammer dustproof structures to improve the service life of breaking hammer to the above problems existing in prior art.
[0004] The utility model discloses a kind of breaking hammer dustproof structures, the breaking hammer includes drill rod and the outer sleeve matched with drill rod, it is characterized in that, the drill rod is tightly equipped with dust cover, the dust cover end face is radially expanded and abuts on outer sleeve, the dust cover is equipped with tight enclosure, the tight enclosure is equipped with multiple clamps in sleeve.
[0005] Compared with prior art, the breaking hammer dustproof structure has the advantages of good dustproof effect and improved overall service life. BRIEF DESCRIPTION OF DRAWINGS

[0009] In the drawing, 1, drill rod;2, outer sleeve;3, dust cover;4, tight enclosure;5, clamp. DETAILED DESCRIPTION
[0010] The following is the specific embodiment of the utility model and is further described the technical scheme of the utility model in combination with the drawings, but the utility model is not limited to these embodiments.
[0011] As Figure 1 , Figure 2 , Figure 3As shown, the dustproof structure of the breaking hammer comprises a drill rod 1 and a sleeve 2 matched with the drill rod 1, and a dustproof sleeve 3 is tightly matched on the drill rod 1, the end surface of the dustproof sleeve 3 is radially expanded outward and abuts against the sleeve 2, in the process of back and forth impact of the drill rod 1, the dustproof sleeve 3 moves with the drill rod 1, the end surface of the dustproof sleeve 3 tightly abuts against the sleeve 2 when the drill rod 1 impacts back, seals the wear gap between the sleeve 2 and the drill rod 1, prevents dust particles from entering, the dustproof sleeve 3 is provided with a tight trapping groove 4, a plurality of clamps 5 are sleeved in the tight trapping groove 4, and the dustproof sleeve 3 is stably connected on the drill rod 1 through the plurality of clamps 5.
[0012] The specific embodiments described herein are merely illustrative of the spirit of the present application. Those skilled in the art to which the present application belongs can make various modifications or supplements to the described specific embodiments or replace them with similar ways, but will not deviate from the spirit of the present application or exceed the scope defined by the appended claims.
[0013] Although the terms such as drill rod 1, sleeve 2, dustproof sleeve 3, tight trapping groove 4 and clamp 5 are used more frequently herein, the possibility of using other terms is not excluded. The use of these terms is only for more convenient description and explanation of the essence of the present application; any kind of additional limitation is contrary to the spirit of the present application.
